1m Contouring Using Satellite Imagery


Need More information ?

The Digital Elevation Model (DEM) is a very important pre condition for many applications such as Map Generation, three dimensional GIS environmental monitoring, geospatial analysis and many more. In addition,   continuous growth in telecommunication and Engineering industries has created even greater demand for DEM data. This data allows Engineers to plan and manage infrastructure growth with the high accuracy required by new spatial applications.




We have undertaken and successfully completed DEM data preparation for following Projects


Project Institute Extent
Matara to Kataragama Railway Development Project Ministry of Transport 2000 km2
Northern Expressway Project (From Colombo – Kandy – Kurunegala ) SMEC International/RDA 1300 km2
Southern Expressway Development Project (From Matara – Beliatta ) Road Development Authority 300 km2
Mundeni Aru Basin Development Project Irrigation Department 1000 km2
Lalan Rubber Mapping Project Lalan Rubber Ltd 210 km2
